My research determines the effects of natural and anthropogenic contaminants in the environment and has a strong focus on the influence of chemical and physical characteristics of water, sediments and soils on metal bioavailability and toxicity to aquatic organisms. In the natural environment, toxicant concentrations usually fluctuate and are dependent on sources. Therefore, the usual method of using constant exposures in a laboratory setting is not always relevant. In addition, research conducted in laboratory usually examines the effects of single contaminant on individual organism. However, the effects of contaminants in the natural environment are often up to community levels. My research uses traditional constant and fluctuating exposure methods to determine the effects of contaminants (single and mixtures) at both individual and community levels using field relevant study design, such as outdoor microcosms.
Results of my research support the development of environmental water quality criteria and the restoration efforts for imperiled ecosystems. By studying the fate of contaminants and responses of organisms, I hope to add to our understanding of how contaminants affect the environment and how we might ameliorate their negative effects in our world.
